A motor vehicle servomotor arrangement includes an electric motor with a stator, a rotor and brushes, as well as a controller with a signal input and a signal output that is connected to the electric motor. The controller is configured to transmit a control signal to the electric motor in response to an input signal supplied via the signal input by a unique function. The controller is configured to modulate the control signal in such a way that different control signals are output upon successive identical input signals within predefined input signal ranges and/or time-variant control signals are output upon identical input signals.
